010 Editor - Text/Hex Editor Homepage

The Color Options dialog allows control over many colors in the Editor Window (see Using the Text Editor and Using the Hex Editor for more information). Open the Color Options dialog by clicking 'Tools > Options...' and selecting Colors from the list.

Many of the color options have a Foreground color (Fore) and a Background color (Back) that are used when drawing text on the screen. The Foreground color indicates the color of the text, and the background color indicates the color of the background behind the text. Usually darker colors are used for the foreground and lighter colors are used for the background.

Click on a color box to open up the Color Selector Box. Select a color from the box, or click the More Colors... button to open the standard Color Selector Dialog. When using the Color Selector Dialog, select a color from either the color boxes on the left or the color area on the right and click the OK button. Clicking the Add to Custom Colors button adds the current color to the list of 16 colors on the bottom left. The Cancel button will close the dialog without selecting a color. Some colors may be set to None, which means that the foreground or background color will not be modified.

The following lists each of the color options and what they control:


Editor Colors

  • Editor - Indicates the foreground and background colors of the main Editor Window. The default is black text on a white background.

  • Modified - When bytes are modified in the Hex Editor, the colors of those bytes are changed. By default, the text color is changed to orange and the background color remains unchanged.

  • Selected - After selecting a set of bytes (see Selecting Bytes), the colors of those bytes are modified. By default, the text color is changed to white and the background to blue.

  • Addresses - Specifies the color of the addresses along the left side of the Text Editor or Hex Editor Window. By default, the text color is black and the background color is the window color.

  • Ruler - Indicates the color of the ruler along the top of each Editor Window (when enabled). By default, the foreground color is black and the background is the window color.

  • Highlighting - This highlighting color is used when highlighting a set of bytes using 'View > Highlighting' (see Working with File Interfaces for more information).

  • Find - After clicking the Find All button in the Find Dialog (see Using Find), all occurrences in the file that match the target are colored according to this rule.

  • Difference - After performing a comparison between two files (see Comparing Files), those bytes that are different between the files will be colored. This option controls which color will be applied to the bytes in the Hex Editor Window.

  • Only In - After a comparison between two files (see Comparing Files), bytes that are only in one file and not the other will be colored according to this rule.

  • Input Method Editor - Some languages use an Input Method Editor (IME) to insert characters into the Editor Window. When the IME is displayed, its color will be controlled by this option.

The following colors are displayed on the right side of the dialog and only have a single color box:
  • Alternating Hex Lines - When using the Hex Editor, alternating lines are displayed in a different color (by default light blue). Change this color to match the Editor background color to obtain a single color in the background.

  • Separator - The Separator is the line that separates the left area from the right area in a Hex Editor Window. Click this color to change the Separator color. The default color is light gray.

  • Highlight Line - By default, the line the cursor is located on will be colored yellow. Click this color to change to a different color. The Highlight Line option can be turned on or off (see Editor Options).

  • Highlight Byte - When the cursor is in the left or the right editing areas, the current byte will be highlighted in the other editing area. The byte is colored light gray by default, but can be changed by clicking the color box.

  • Highlight Variable - After a Template has been run on a file, moving the mouse over the Hex Editor Window will cause brackets to display indicating where the template variables were declared (see Working with Template Results). The color of the brackets can be modified by clicking this color box (the default color is dark gray). The Highlight Variable option can be turned on or off using the Hex Editor Options dialog.

  • Right Area - The color to the far right of both editing areas in the Hex Editor Window can be controlled by clicking this color box. The default color is the color of the window.

  • Division Lines - Division Lines are lines that are drawn on the Hex Editor Window that indicate groups of bytes. By default, Division Lines are drawn every 4 bytes and they are colored light gray. Use the 'View > Division Lines' menu to adjust the division lines (see Working with File Interfaces). Clicking this color box allows changing the color of the Division Lines.

  • Sector Lines - Sector Lines are similar to Division Lines except they are usually used to visualize where sectors are located on a drive. Sector Lines can be controlled on the same menu as Division Lines 'View > Division Lines' (see Working with File Interfaces). The color of the sector lines can be changed from the default dark gray using this color box.

  • Status Warning - If an error occurs when performing an operation, an error message is sometimes displayed in the Status Bar. The background of the error message will be displayed as this color (by default orange).

  • Ruler Column Marker - The color of the small arrow which indicates the current column in the Text Editor Window ruler can be controlled with this option. The default color is gray.

  • Caret - This option controls the color of the caret (the blinking cursor) in either the Hex Editor or Text Editor Window. The default color is black.

Clicking the Reset button will return all of the colors to their default values.
